Re: KSK signing zone records
Named will continually re-sign parts of the zone as the RRSIGs for a RRset fall due for replacement. Named looks at which keys are in the active state to determine along with the afore mentioned controls to work out which DNSKEYs will be used to re-sign the RRset. If in the past you only had one key type and you now have two, different keys may be used to re-sign the RRset. If you changed policy in named.conf, the new policy will be implemented as the RRSIGs are re-generated. It looks like you told named to re-sign the zone when there was only one type of DNSKEY key record (or you where unlucky enough for named to check the available keys whiles there was only one active key present) resulting in named overriding the policy in named.conf.

Re: KSK signing zone records
I'm using Algorithm 8 RSA/SHA-256, and Algorithm 14 ECDSA/SHA-384. I have one RSA KSK and one RSA ZSK. In addition I have two ECDSA KSK and two ECDSA ZSK. The RSA KSK seems perfectly happy to sign the ECDSA ZSKs. And both the RSA and ECDSA ZSKs seem to be singing records correctly. It just seems to be the two newer ECDSA KSKs that instead of signing the ZSKs are singing the domain records directly. Even more perplexing is that one of the domains seems to have fixed itself. Now all the KSKs for that domain are singing the ZSKs and the ZSKs are signing the domain records. But I've still got a couple of other domains where it is doing it wrong. Is there some kind of timeout or maintenance that gets run automatically that might have fixed the issue? I've tried running an "rndc sign" command on the domains several times. Timothy A.
